Fibre and textile developer Toray has combined nanotechnology and fibre technology to create a cross-shaped polymethyl methacrylate (PMMA) nanopore fibre that, it claims, can adsorb pathogenic proteins in the blood. 

The Japanese company developed this fibre by employing its PMMA hollow fibre membrane spinning technology. Changing the nanopore size on the surface and inside the fibre makes it possible to control the types of protein that this material adsorbs, Toray said.

It added that this could become “a fundamental blood purification technology” for a range of protein adsorption columns that cause diseases.
